The way you use it is very simple. For example, to do a `GET` request, you would write:

```Python
response = requests.get("http://example.com/some/url")
```

The FastAPI counterpart API *path operation* could look like:

```Python hl_lines="1"
@app.get("/some/url")
def read_url():
    return {"message": "Hello World"}
```

See the similarities in `requests.get(...)` and `@app.get(...)`.

disable the `permessage-deflate` compression settings on your server.

Note that OkHttp won't use compression when sending messages smaller than 1 KiB.

这就是为什么，正如其官网所说：

> Requests 是有史以来下载量最高的 Python 包之一

它的用法非常简单。例如，进行一次 `GET` 请求，你会这样写：

```Python
response = requests.get("http://example.com/some/url")
```

对应地，FastAPI 的 API 路径操作可能看起来是这样的：

```Python hl_lines="1"
@app.get("/some/url")
def read_url():
    return {"message": "Hello World"}
```

可以看到 `requests.get(...)` 与 `@app.get(...)` 的相似之处。

/// check | 启发 **FastAPI**：

* **경로**: 는 `/`입니다.
* **작동**: 은 `get`입니다.
* **함수**: 는 "데코레이터" 아래에 있는 함수입니다 (`@app.get("/")` 아래).

{* ../../docs_src/first_steps/tutorial001_py310.py hl[7] *}

이것은 파이썬 함수입니다.

URL "`/`"에 대한 `GET` 작동을 사용하는 요청을 받을 때마다 **FastAPI**에 의해 호출됩니다.

위의 예시에서 이 함수는 `async`(비동기) 함수입니다.

`async def`을 이용하는 대신 일반 함수로 정의할 수 있습니다:

{* ../../docs_src/first_steps/tutorial003_py310.py hl[7] *}

# 設定與環境變數 { #settings-and-environment-variables }

在許多情況下，你的應用程式可能需要一些外部設定或組態，例如密鑰、資料庫憑證、電子郵件服務的憑證等。

這些設定大多是可變的（可能會改變），像是資料庫 URL。也有許多可能是敏感資訊，例如密鑰。

因此，通常會透過環境變數提供這些設定，讓應用程式去讀取。

/// tip

若想了解環境變數，你可以閱讀[環境變數](../environment-variables.md)。

///

## 型別與驗證 { #types-and-validation }

這些環境變數只能處理文字字串，因為它們在 Python 之外，必須與其他程式與系統的其餘部分相容（甚至跨作業系統，如 Linux、Windows、macOS）。

這表示在 Python 中自環境變數讀取到的任何值都會是 `str`，而任何轉型成其他型別或驗證都必須在程式碼中完成。
